The Walker stainless steel Quiet-Flow Muffler has been developed to provide the top-grade performance you expect from one of the world's leading emissions control companies. This is the only broad market replacement muffler that resists rusting three times longer than premium aluminized mufflers. This part's internal design features bridge construction, durable internal partitions, strong interior spot welds, and special position of the inner shell and outer cover lockseams to improve the muffler's structural stability, strength, and make sure it will last much longer.

To allow OE-quality and factory-style acoustic performance, the muffler is constructed using louvered tube technology, CRF technology, and features three-tube design. Internal tubes are mechanically joined to the partition to allow free-floating expansion and contraction during temperature changes. This elaborate design eliminates the breaking of spot welds, subsequent part deformation, or loose part noise troubles. All stainless steel structure and perfected interior construction make the Quiet-Flow Muffler one of the most advanced, premium designs available today.
